Abstract: The CPC led the people to form a great "trolley" spirit in the Huaihai Campaign. The spirit of "trolley" is a true portrayal of "listening to the Party's command, pursuing truth, not afraid of sacrifice, considering the overall situation, firm ideals, and forge ahead", which fully reflects the Chinese people's spirit of seeking truth, dedication, and enterprising spirit. The spirit of "trolley" should be integrated into the teaching of outline courses, and academic research should be combined with classroom teaching to enhance theoretical and affinity. We should adhere to the combination of knowledge transmission and thinking guidance to enhance the transmission and inspiration. And we should adhere to the unity of teaching mode and teaching effect to enhance pertinence and diversity.
